Wickham Green too Posted June 20, 2020 Share Posted June 20, 2020 The balance pipe to ensure even weight distribution could be problematic ! 1 Link to post Share on other sites More sharing options...
RMweb Gold tomparryharry Posted June 20, 2020 RMweb Gold Share Posted June 20, 2020 There's 3 balance pipes. one between the 2 side tanks, and the 2 pipes, which tun from the bunker tank, to either tanks. I'd guess you would use the bunker tank as fuel, with the other remaining as water use. Link to post Share on other sites More sharing options...
Wickham Green too Posted June 21, 2020 Share Posted June 21, 2020 With an eight-wheel bunker tank you'd probably carry enough fuel to get from Penzance to Thurso an' back ......... stopping every ten miles for water, of course. 1 Link to post Share on other sites More sharing options...

Which would give the fireman time to shovel coal forward over the zig-zag floor of the bunker. Link to post Share on other sites More sharing options...

autocoach Posted June 22, 2020 Share Posted June 22, 2020 A Mallet has a mix of high pressure and low pressure cylinders reusing the steam on a usually articulated wheel arrangement. Otherwise if steam goes directly to both (or in some cases 3) sets of drivers it is just a simple articulated. The Mallet name is capitalized as it is named for the French designer of the high/low steam arrangement on an articulated rather than a compound. It was the Erie Railroad triplex 2-8-8-8-2 (https://en.wikipedia.org/wiki/Triplex_(locomotive) that really caused a bit of stir. Link to post Share on other sites More sharing options...

Somewhere on YouTube is a 7 inch gauge live steamer of one of those in action, fascinating to watch a listen to. Link to post Share on other sites More sharing options...

Of course, it does depend on where the proposed oil tank would go. It's funny, but when the VoR locomotives were converted, much work was done to disguise the oil tank. Nobody noticed for quite a long while. Link to post Share on other sites More sharing options...

And very nice it was too although the articulated was a simple, not a Mallet (and I did manage a ride behind it on one of my visits). a great shame taht Dobwalls closed but it might have been financial as JohnSouthern ploufghed a huge amount of money into the railway and the motive power. https://en.wikipedia.org/wiki/Dobwalls_Adventure_Park And while you need to exercise patience it does appear working a train on this 'home movie' style video - https://www.youtube.com/watch?v=Cnmw3YJhtqg And on this one - https://www.youtube.com/watch?v=pEXZ_fC03dY Link to post Share on other sites More sharing options...

The only one I could find is this video from Train Mountain. Wow, that looks impressive... Even then the title refers to a Triplex, but it isn't. The Triplex is shown in two parts of the video and it's not clear if the loco pulling is the Triplex or another Big Boy or similar... Not sure if I'll ever get to the US again, but Train Mountain will be on my list of places to go. The Americans really are spoilt for space...... Edit. Just watched again and the guy in the check shirt driving is in charge of the Triplex. The loco pulling alongside in the first few minutes threw me......

That's the beast, plenty of time lost looking at some of the footage, as you say Gordon, spoilt for space, just like the modelling. Link to post Share on other sites More sharing options...
